Here are some things Steven Universe got wrong (Geology wise)

Gems are objects and is confirmed that they do not have genders but Rebecca also confirmed that they are lesbian. How can objects show sexual relations with each other

Bismuth is a metal not a gem

Diamonds and Quartzs are in different crystal families and are not the same

There are other colours of Sapphires then ablue

Rubies are the most precious gems so why aren’t they in charge

Diamonds are primarily clear but natural coloured diamonds are usually shades of brown or tan
